That's a cool concept, but would it be worth 2-3 times the price of a typical magazine? I don't own an AR, so my knowledge of prices is the result of a google search I just did, but it doesn't seem worth it. Maybe just a Bug Out or HD loadout, rather than replacing all magazines with it?

Never hit first. Always hit back.

The only thing worse than a zombie trying to eat you, is a zombie trying to eat you while it is on fire.

At $21 per mag that does not seem unreasonable to me but if I remember the last time I bought polymer mags they were around $17.I have not bought in a while though, I have so many AR mags I may only buy technologically innovative ones for the rest of my life.Basically I have enough to deal with the drug dealer across the street and all his friends.

The only issue I see with these is in the consistency of training.For the last 20 years or so, I have developed the muscle memory for standard mags. Last round bolt hold open, drop the mag, insert a fresh one, close the bolt, BANG!It works.It's what I'm used to.My mags all work flawlessly.

Right now you can get standard Pmags/Lancers/Troys for $12-$15. USGIs for $9-12.

I don't really see where these new mags offer anything better.
